ABSTRACT:
A tomosynthesis system for scanning a region in an object comprises a radiation source configured to traverse in a plurality of positions yielding a plurality of scanning directions. Each of the plurality of positions corresponds to a respective scanning direction. Further, the plurality of scanning directions comprise at least a scanning direction along a first axis and a direction along a second axis, the second axis being transverse to the first axis.
